Just bought a D150 with a slant 6 in it, so now I'm going back through all the slant six and truck videos you have. I did the same thing when I got my 66 Barracuda. Your video's really encourage old Chrysler ownership!
FACT : I had MANY A and B body 225 ' s and 318 ' s the ONLY mileage difference i got ( with identical trans. and rears ) is 2 M.P.G. ! and a 318 has MUCH more horsepower and a little more torque .
My first car was a 1979 Dodge Aspen with the Super Six in it and I drove the heck out of that thing but it was already beat on before I bought it for a whole 300 bucks the guy who owned it before me beat he tar out of it but it still ran great it lasted me two years before I got another car and it had nothing to do with the engine it ran good still but it was getting rusty and it was time for me to buy another cheap car that had less rust on it.

My dad bought a 68 Valiant 100 segnent or something like that 2 door brand new with a 225 Slant six automatic on the column, no air conditioning, and that engine went through three bodies that completely rusted off the frame. The engine total about 390,000 miles with no internal maintenance, just oil change every 3000 Miles religiously. What a car, what motor.
383,426,440 V8 are still all time favorites with Mopar fans, sadly enough the slant sixes only reputation was being highly dependable for taxi cabs, but had so much more to offer.
My second car was a '71 Duster (bought from my brother for $100 in 1981-82) with a 225. Would like to have another (slant or 318 V8 would be fine for a daily driver).
My Dad (RIP) had a 1978 LeBaron sedan with the Super Six. Of course, the EPA smog system choked it. My Dad and our next door neighbor took the 2bbl off and put in different jets. I don't know what they did but, it definitely felt peppier and probably gave it an honest 120hp at the rear wheels as opposed to the claimed 110 hp in EPA form. The fuel economy dropped a bit but, the performance improvement was worth it.

From 1961-1963 over 50,000 225 slant 6 engines were made with aluminum engine blocks . . The hyper Pak slant 6 was quite different from the standard production 6 cylinder. It's worth looking this up and reading the story behind it. Quite humorous actually, because it beat all other manufacturers cars in the same class, and even ran down a 283 Chevrolet fuelie in the flying mile in the process. The leaning tower of power we called them in the 70s. They were actually quite economical as Factory compact cars, worthy of note that many of them had better mileage then some cars today and that was 50 years ago. Most of the 1970 Dodge Dart models with the slant 6 would achieve mid-twenties in mileage per gallon and only cost $2,500 brand new.

I had a 1979 Aspen with a slant 6. I had the cylinder head redone. Two cylinders had no compression due to bad valves. I do not know why valves burnt out, but maybe because i never adjusted the valves as required due to it having solid lifters or using cheap gas? I think this was about the time unleaded gas & catalytic converters came in too. After reinstalling the head - the choke was not working. I finally discovered a wire had come loose near the starter motor - that works I believe to heat up the intake manifold for the choke to work? The car rusted out bad in Michigan & had less than 100,000 miles when I gave it to a family member years ago.
There is a big difference between the standard Slant 6 and the Super 6. I attended the Mopar school in 1977 and the instructor informed us. The Super 6 1.)has the BBD carb which is not the same as used on the 318. The Super 6 carb has a thicker carb wall, and 2.)the exhaust system used larger diameter pipe.
Love my 225 slant 6, want to put a hyper pak on it, but OG slant 6's are faster then later models, the newer models start at like 80hp but old one 145hp with 215lbs of torque to start
We had Chrysler Valiants in NZ in 60s & 70s with slant 6 and the badge on back fender said 160 HP , they looked different in stile my uncle had one he loved it. As a boy i remember it would sit you back in the seat with acceleration.
Wait… So I could put a 2 barrel carb on my 67 w100 truck? It’s got the 225 slant 6? Can you give me some suggestions please? I’m just learning about my “new” truck and it’s crooked little motor…
Wow...that head was originally on a very early aluminum slant six. What kind of block is it on now? No performance increase but produced to tighter tolerances to maintain head gasket integrity.
@@carlospuckett3161 yeah do some digging around and you probably can come up with the aluminum 225 block from the early 60s. Probably would be worth putting that engine together if you can find all the original parts. I would bet that head is harder to come by then the aluminum block
Miss my slantie, really good for gas mileage, do have a 225 mated to a 4spd in a '84 D100. Think the throw out bearing may have let go, but will be installing an HEI conversion in it. That was a good idea, Tyler. Thanks.
I speculate that Chrysler Corp would not build a better performing slant six because it was cheaper to sell a V-8. Customers looking for better performance probably wanted a V-8. The hyperpak days in the early 60,s were when the Ford Falcon and Chevy Corvair could only be had with a six, so Chrysler hopped up the slant six and beat the competition at the track every weekend.
ALL the domestic "compact" cars were actually COMPACT. Look at how much bigger the Dart got by 1967. So did the Valiant, but it did have the smaller wheelbase. That and, by 1974, requiring more frame "beefing" and those huge 5 mph bumpers added a lot of weight. Coupled with the engines being strangled due to ill-fitting emissions control systems, this made the post-1973 A-bodies and later F-body cars rather "tame" and uninteresting, if equipped with a Slanty. The 170 was on a shorter block than the 225, in 1970, this engine and "LG" block was discontinued, to use the "RG" block that accommodated the 225' crank throw of 4.125 in stroke (which made the 225 a very "undersquare" design for post-WWII standards), "splitting the difference" with a 3.625 in stroke, to produce the 198. This was done primarily to keep the 225 as an 'optional' engine in the A-bodies, i.e, MORE MONEY, and in '70 and '71, the 198 was adequate for stripped-down entry level Darts, Dusters, and Valiants, especially with stick shift. The 198 did come with a A904 Torqueflite, but I'm sure that if you wanted power steering and/or A/C, you had to get the 225. Once the smog era was on, the 198 was way too "gutless" to be a credible engine for even the A-bodies, so 1974 was its last year. The only trouble with the V8 options were that they, too, were getting strangled and more gutless with emissions. The "Net" rating on the 318 2bbl, which was the only optional V8 on the Dart Custom and the Valiant Brougham, was rated as of 1972 at 150 ponies. By the 1980 model year, the last of the succeeding F-body cars (Aspen and Volare), that engine was down to 130 hp! In the Dart "Demon" model (badge-engineered Duster), you could get the 340 4bbl, which had 270 ponies (underrated, for insurance purposes, more like 315 to 320) in 1970, and still cranked out about 225 hp in 1972 and 1973, but was discontinued as "hot rods" were being discouraged by Washington. It was replaced in 1974 by the 360 4bbl, which was rated at 175 hp, with a more "docile" cam more suited for the B and C body cars it was intended for. Since the ratings were "Net" rather than "Gross", they more accurately reflected what one could actually expect, but they also were at LOWER rpms, which, given the emissions that hobbled performance, was also more truthful.
Yes! I had a '69 Valiant. Yes, it was a 170 cu.in. NO, it was not reliable or dependable... It sat most of it first six years. Yes, the 170 could really take off quick and boogie!!!! 3 on the tree car!
Is it true that if you just got ahold of one of those stickers and stuck it on a 198 car's air cleaner housing, that you'd get up to 60 mph a few tenths of a second more quickly?
Got the same car, started blowing smoke like the movie on Uncle Buck, and lost compression Big Time, all of a sudden...before when it was running good, the motor sounded like a singer sewing machine, and ran good, well I had to move, and the moving guy must have revved the eng and when I have gone to crank it, it smoked but ran, thinking it must have blown a head gasket I have gone to take it apart to replace the head gasket and 2 push rods was just laying there not connected. So took off the camshaft and got new rods coming, now looking for a vid to install the rods and camshaft for this same car... and thinking back, the sewing machine clicking. Meant that they needed to be adjusted, I learned how to do that, but not replacing the push rods, and tightening the bolts down when adding new rods, any advice? hold each rod in place and tighten down the bolts till they are firm then run the eng till warm, then adjust the lifters with a filler gauge is all i can think of it seems, not much info out there on these, 225 slant 6 mine is just like yours a 68 :)
Every time I hear super six I feel bad cause I tried my best to sell a super six that came with my 72 dart not the original engine...but nobody wanted it for $200 and it went to scrap with transmission! Shame ran like a champ.
Years ago I found a Feather Duster at the junkyard that had a Super Six in it. So I bought the induction system and swapped out my 1bbl on a 225. The car not only went slower, but got worse fuel mileage. I still don't know why.
I'm restoring my 69 Dart w/a 225 - Buzzin 1/2 dozen ,,,could you do a video on the anti icing heat tube configuration? Can't find any info whatsoever on it ,,thanks .
I would if I had any info on it. I think i found one diagram of how it worked somewhere...I will look for that page and post the link. Those were a canadian thing that someone at Chrysler thought needed to be implemented on US cars. Apparently not. I have a 69 manifold somewhere in my stash.
If you'll go down this page a little over halfway, there's a diagram of how the system is hooked to the air cleaner and carb. Now i remember that they stopped using this system because they began using the air cleaners that had a hot air tube going up to the snorkel. Also, your Slant six is supposed to be a 1-year only medium metallic blue 🙂. Before that they were red, afterward they were Chrysler Blue. www.motales.com/engines/slantsix.php
@whosaidtyler thanks very much there was a wealth of information on that page ,,,my /6 is medium blue ,,I just did a valve job on her so she should run better ,,I had to rebuild her heat tube configuration because I live in Colorado & it can get below 0 ,,also her exhaust manifold heat control valve siezed up & the thermostat spring broke so i had to repair all that ,,,once again thanks for your help that helped me big time .
@@steveroberson1488 There are some on ebay now, and Rock Auto carries them, they are in the ignition category with spark plugs. Not sure how long those will remain available.
Iv got my self a 68 valiant and if it wasn't for the 225 i wouldn't have got it iv also got a 83 ram short bed 225 and a 4 speed. By far my favorite engine ever made. The valiant gets around 17mpg
I agree about the foreign countries get all the neat stuff. Diesels, manual transmissions (which is basically dead in this country now) and other stuff. I don't get it either.
The lid on that air cleaner will house a 10" element, as well as the 8" element on 1-barrel bases. If you want to upgrade to a 4-barrel carburetor, just get an aftermarket four-barrel base that holds a 10" element and you're golden!
I was kind of hoping, after you'd noted that a lot of cool stuff was exported and not sold on the domestic market, that someone besides little old me would have mentioned that Chrysler Australia sold a Hemi head inline six in their compact cars. I've wanted one since I heard about them so I could reply, "Hell yeah, it's a HEMI!"
My Dad (RIP) had a 1978 LeBaron sedan with the Super Six. Of course, the EPA smog system choked it. My Dad and our next door neighbor took the 2bbl off and put in different jets. I don't know what they did but, it definitely felt peppier and probably gave it an honest 120hp at the rear wheels as opposed to the claimed 110 hp in EPA form. The fuel economy dropped a bit but, the performance improvement was worth it.
The "Super 225" name was used on Plymouths and the "Charger 225" name was used on Dodges. They are otherwise identical engines. The Super Six was not available in the USA until the late 1970s because Chrysler did not want to cut into sales of the more expensive and powerful V8 engines.
Plymouth had the Super 225 and Dodge had the Charger 225 and starting in 76 or 77 Chrysler put a 2bbl carb on the 225 and called it the Super Six and the only difference was the the intake and carb one had a single barrel and the other had a 2bbl intake and carb. The 2bbl carb was the same carb the 318 ran on it. It did not run the big 2 bbl like you would of found on the 360 CI engine.
Yeah we had a '68 Dart with a 225, and it said "CHARGER 225" on the air cleaner. Speaking of air cleaners you can fit a 10" element under one of those lids. If you buy an aftermarket base for a four-barrel carburetor with a 10" element, you can use those lids. That's what I'll be doing for the 225 in my '80 Mirada.
I had a 70 valiant 4 door sedan and mine had a 198 slant 6 no one seems to talk about the 198 for some reason it was rated at 125hp. The 225 was 145hp. And I don't think the 170 was available for 70' I think the 198 replaced the 170.
Not sure about the difference, but the first one needs the pushrods adjusted rather badly. The later Super Six was a 2bbl carburetor. The 170 was standard engine in Valiant, Lancer, and later Dart. There was also a 194 variant. Having lived with 225 slant sixes, you are welcome to them. The 318 V8 gets better gas mileage and can get out of its own way.
Sweet car. I love the fact that it still has the original wheels, tires, and wheel covers on it. PLEASE don't put 22" GHETTOs on it. I would love to have that as a daily driver, IF it had A/C in it. I live in Phoenix, AZ, and for half the year A/C is an absolute necessity, not a luxury.
Actually, Chrysler feared the same thing that GM feared in the Pontiac OHC Sixes...that beefing them up would take away from more profitable V8 engine "upgrades", which typically were sold as part of a "package". That's where the PROFIT was in car sales. A "Super Six" simply didn't command as much money as a V8, even the "doggish" 318 2 bbl that seemed to power almost everything that Ma Mopar put out.
In 1960, the Plymouth Valiant had the 170 cubic inch as standard the 1969 year was the last year for the 170, Chrysler replaced the 170 with 198 cubic inch engine in 1970 then in 1980 dropped the 198 and only the 225 until it was dropped in 1987
As an owner of 2 cars with 20 years between them, I love the modern touchscreen and sensors etc, but love my old mk1 focus from 1999. If you didn't have a modern car from work, would you ever own one or would you stick with the classics as a main car?
I had a Super Six in a 1979 Chrysler LeBaron. It was the dirtiest running engine I ever had. If you left it idling in the driveway for 5 minutes there would be a little pile of soot under the tailpipe. If you stepped on it to pass someone and it downshifted there would be a giant cloud of black smoke coming out the back. I was just a kid in college at the time so I never had it looked at but I assume it was running super rich. It also only got 10-14 mpg depending on city or highway. It was a bit disheartening to only get 180 miles out of an 18 gallon tank.
Thats what my current 75 Dodge D100 is doing right now, about 10mpg on a rebuilt engine with the black tail pipe soot marks left on driveway as well. Have messed with the timing to no improvement; only thing I have not done yet is rebuilt the carb which is next on my list as soon as I get back from my deployment.
@@chadfield376 the choke pull off if I remember correctly has a vacuum that moves a mechanical linkage to keep the butterfly from completely closing while the choke is engaged.
The electric choke that Chrysler had in the late 1970s were horrible. I had a 1980 Aspen and found it best if you didn't press the throttle until it was fully warmed up or you were on the highway cruising. Did I see black smoke? Definitely! But if you pressed the throttle before it was warmed up, it would almost totally disengage the choke and you were left with a bogging engine when you tried to drive off again. I remember manually shifting the automatic in order to get going. What a pig. Everyone blamed Chrysler, but it was once again the Federal US government sticking their nose in their business for "cleaner air quality". Ironically, I believe that my 3 other older slant six engines that I owned with mechanical chokes were more cleaner for the environment and didn't have the problem.
According to "Uncle Tony", the 170's 3-13/32 bore by 3-1/8 stroke are just about perfect for that engine. That yields roughly a 10:9 bore to stroke ratio, which many engine designers say is the "ideal" for a modern engine.
40 year's ago a friend bought a orange Dodge Charger that had 4 screws sticking up on the roof and the doors had oblong tale tell signs signaling that there had been a sticker on each side. Ok, I'll get to the point. It had been an Orkin Pest Control company car at one time. He didn't think much of his temporary cheep transportation and agreed to sell it to me when he got more money and got a new ride. I loved that car. Well, just about time he was fixing to get another car and sell the Charger to me the dumb butt got drunk, passed out at the beach, and a lowlife friend of his took off with a girl he'd picked up for a short joy ride and wrecked it bad. I was sick. It was not to be. I later got a 72 or 4, can't remember, Duster rust bucket northern car with the mighty slant 6 and had fun with it until it just about turned to solid rust. That's my story.
You got that right! You can take 100 thousandth off the head and get ride of that broomstick cam,dual exhaust and 2bl carb 4sp Tran 10.25 tempest clutch and you will scare the s__t out of your friends with 225. You will out rev 'em. It's the same comparison 170 vr 225 as 283 vr 327. Ask Joe Alread, look him up, he beat a lot of 327s
My 83 d150 gets 22- 24 mpg. 4 speed OD manual, 2 bbl carb with out any lean burn. And thats with a worn out engine that burns 1 quart of oil in 200 miles and not enough compression to park on ANY incline in gear with out it rolling down hill.
@@TylersNeighborhoodGarage I *was* thinking about improving the “long and slanty” in the Dodge that way. Alas, accidents happen, and my health was starting to go then anyway…
Different days back in the 60s and much of the 70s. In that time, sixes were considered old faithful economy engines. Comptrollers and other frugal minded people/cheapskates bought them.
The reason other countries got the better deals and different carbs and such is because we started the emissions crap in 1964 with the advent of the pcv valve but progressively got worse year after year Canada didn't even start any emissions until the late 70s. The aussies didn't start until the late 80 s were the only country burdened with this crap anyway to the extent that no other country comes close to

I had the cylinder head redone.
Two cylinders had no compression due to bad valves. I do not know why valves burnt out, but maybe because i never adjusted the valves as required due to it having solid lifters or using cheap gas?
I think this was about the time unleaded gas & catalytic converters came in too.
After reinstalling the head - the choke was not working.
I finally discovered a wire had come loose near the starter motor - that works I believe to heat up the intake manifold for the choke to work?
The car rusted out bad in Michigan & had less than 100,000 miles when I gave it to a family member years ago.
There is a big difference between the standard Slant 6 and the Super 6. I attended the Mopar school in 1977 and the instructor informed us. The Super 6 1.)has the BBD carb which is not the same as used on the 318. The Super 6 carb has a thicker carb wall, and 2.)the exhaust system used larger diameter pipe.
Love my 225 slant 6, want to put a hyper pak on it, but OG slant 6's are faster then later models, the newer models start at like 80hp but old one 145hp with 215lbs of torque to start
Net vs Gross output..
We had Chrysler Valiants in NZ in 60s & 70s with slant 6 and the badge on back fender said 160 HP , they looked different in stile my uncle had one he loved it. As a boy i remember it would sit you back in the seat with acceleration.
That more powerful one was the Formula S. Twin barrel Carter carb.
my mom had a 1971 green 4dr valiant very reliable car!
Wait… So I could put a 2 barrel carb on my 67 w100 truck? It’s got the 225 slant 6? Can you give me some suggestions please? I’m just learning about my “new” truck and it’s crooked little motor…
As long as you use a 2bbl intake. Those are usually found on early 80's trucks and vans. The improvement is more emotional than physical however.
I have a 225 in my dart.The head has the word special stamped on it.Could you tell me what that means.thankyou.
Wow...that head was originally on a very early aluminum slant six. What kind of block is it on now? No performance increase but produced to tighter tolerances to maintain head gasket integrity.
@@TylersNeighborhoodGarage I bought the head rebeuilt .for my 67 Dodge dart.Thanks now I know it's history.thank you very much.
@@carlospuckett3161 yeah do some digging around and you probably can come up with the aluminum 225 block from the early 60s. Probably would be worth putting that engine together if you can find all the original parts. I would bet that head is harder to come by then the aluminum block
Miss my slantie, really good for gas mileage, do have a 225 mated to a 4spd in a '84 D100. Think the throw out bearing may have let go, but will be installing an HEI conversion in it. That was a good idea, Tyler. Thanks.
Could you do an explanation video of the anti icing exhaust manifold heat tube & the connections to the carburator ?
Do you know where I can buy a windshield washer reservoir? I have a 70 swinger with a 225 that is missing the reservoir lol.
Easy to find on eBay and other places. Chrysler licenses the reproductions...you won't find a used one.
I speculate that Chrysler Corp would not build a better performing slant six because it was cheaper to sell a V-8. Customers looking for better performance probably wanted a V-8. The hyperpak days in the early 60,s were when the Ford Falcon and Chevy Corvair could only be had with a six, so Chrysler hopped up the slant six and beat the competition at the track every weekend.
ALL the domestic "compact" cars were actually COMPACT. Look at how much bigger the Dart got by 1967. So did the Valiant, but it did have the smaller wheelbase. That and, by 1974, requiring more frame "beefing" and those huge 5 mph bumpers added a lot of weight. Coupled with the engines being strangled due to ill-fitting emissions control systems, this made the post-1973 A-bodies and later F-body cars rather "tame" and uninteresting, if equipped with a Slanty. The 170 was on a shorter block than the 225, in 1970, this engine and "LG" block was discontinued, to use the "RG" block that accommodated the 225' crank throw of 4.125 in stroke (which made the 225 a very "undersquare" design for post-WWII standards), "splitting the difference" with a 3.625 in stroke, to produce the 198. This was done primarily to keep the 225 as an 'optional' engine in the A-bodies, i.e, MORE MONEY, and in '70 and '71, the 198 was adequate for stripped-down entry level Darts, Dusters, and Valiants, especially with stick shift. The 198 did come with a A904 Torqueflite, but I'm sure that if you wanted power steering and/or A/C, you had to get the 225. Once the smog era was on, the 198 was way too "gutless" to be a credible engine for even the A-bodies, so 1974 was its last year.
The only trouble with the V8 options were that they, too, were getting strangled and more gutless with emissions. The "Net" rating on the 318 2bbl, which was the only optional V8 on the Dart Custom and the Valiant Brougham, was rated as of 1972 at 150 ponies. By the 1980 model year, the last of the succeeding F-body cars (Aspen and Volare), that engine was down to 130 hp! In the Dart "Demon" model (badge-engineered Duster), you could get the 340 4bbl, which had 270 ponies (underrated, for insurance purposes, more like 315 to 320) in 1970, and still cranked out about 225 hp in 1972 and 1973, but was discontinued as "hot rods" were being discouraged by Washington. It was replaced in 1974 by the 360 4bbl, which was rated at 175 hp, with a more "docile" cam more suited for the B and C body cars it was intended for. Since the ratings were "Net" rather than "Gross", they more accurately reflected what one could actually expect, but they also were at LOWER rpms, which, given the emissions that hobbled performance, was also more truthful.
Yes! I had a '69 Valiant.
Yes, it was a 170 cu.in.
NO, it was not reliable or dependable...
It sat most of it first six years.
Yes, the 170 could really take off quick and boogie!!!! 3 on the tree car!
Is it true that if you just got ahold of one of those stickers and stuck it on a 198 car's air cleaner housing, that you'd get up to 60 mph a few tenths of a second more quickly?
Sounds good to me!
Got the same car, started blowing smoke like the movie on Uncle Buck, and lost compression Big Time, all of a sudden...before when it was running good, the motor sounded like a singer sewing machine, and ran good, well I had to move, and the moving guy must have revved the eng and when I have gone to crank it, it smoked but ran, thinking it must have blown a head gasket I have gone to take it apart to replace the head gasket and 2 push rods was just laying there not connected. So took off the camshaft and got new rods coming, now looking for a vid to install the rods and camshaft for this same car...
and thinking back, the sewing machine clicking. Meant that they needed to be adjusted, I learned how to do that, but not replacing the push rods, and tightening the bolts down when adding new rods, any advice? hold each rod in place and tighten down the bolts till they are firm then run the eng till warm, then adjust the lifters with a filler gauge is all i can think of it seems, not much info out there on these, 225 slant 6 mine is just like yours a 68 :)
Every time I hear super six I feel bad cause I tried my best to sell a super six that came with my 72 dart not the original engine...but nobody wanted it for $200 and it went to scrap with transmission! Shame ran like a champ.
Moparnut62, rest assured someone has it now. And were amazed when it fired up with a shot of Starting Fluid!😎
@@brianwells4507 I'm pretty sure that not the one I junked! But they are pretty sweet running straight sixes keep it happy man!
Years ago I found a Feather Duster at the junkyard that had a Super Six in it. So I bought the induction system and swapped out my 1bbl on a 225. The car not only went slower, but got worse fuel mileage. I still don't know why.
Cam couldn't "eat it", plus it could have been a faulty installation, or bad rebuild on the Carter BBD. Have you checked that thing for vacuum leaks?
I'm restoring my 69 Dart w/a 225 - Buzzin 1/2 dozen ,,,could you do a video on the anti icing heat tube configuration? Can't find any info whatsoever on it ,,thanks .
I would if I had any info on it. I think i found one diagram of how it worked somewhere...I will look for that page and post the link. Those were a canadian thing that someone at Chrysler thought needed to be implemented on US cars. Apparently not. I have a 69 manifold somewhere in my stash.
If you'll go down this page a little over halfway, there's a diagram of how the system is hooked to the air cleaner and carb. Now i remember that they stopped using this system because they began using the air cleaners that had a hot air tube going up to the snorkel. Also, your Slant six is supposed to be a 1-year only medium metallic blue 🙂. Before that they were red, afterward they were Chrysler Blue.

@whosaidtyler thanks very much there was a wealth of information on that page ,,,my /6 is medium blue ,,I just did a valve job on her so she should run better ,,I had to rebuild her heat tube configuration because I live in Colorado & it can get below 0 ,,also her exhaust manifold heat control valve siezed up & the thermostat spring broke so i had to repair all that ,,,once again thanks for your help that helped me big time .
@@TylersNeighborhoodGarage Also would you know a source to obtain spark plug tube O -rings ?
@@steveroberson1488 There are some on ebay now, and Rock Auto carries them, they are in the ignition category with spark plugs. Not sure how long those will remain available.
you can do a lot with one of these now, up to and including a super charger.
They did come in 2bbl in the US and Canada.
Iv got my self a 68 valiant and if it wasn't for the 225 i wouldn't have got it iv also got a 83 ram short bed 225 and a 4 speed. By far my favorite engine ever made. The valiant gets around 17mpg
I agree about the foreign countries get all the neat stuff. Diesels, manual transmissions (which is basically dead in this country now) and other stuff. I don't get it either.
true mate in 1968 in aus they had a version called the pacer a slant with 3 speed on the floor and xtra stuff to make 170 hp
i have always wondered about that. My dad's 1967 Dodge Dart said Super 225.
The lid on that air cleaner will house a 10" element, as well as the 8" element on 1-barrel bases. If you want to upgrade to a 4-barrel carburetor, just get an aftermarket four-barrel base that holds a 10" element and you're golden!
Thanks!
@@TylersNeighborhoodGarage Anytime.
Great car, thanks for sharing.
I was kind of hoping, after you'd noted that a lot of cool stuff was exported and not sold on the domestic market, that someone besides little old me would have mentioned that Chrysler Australia sold a Hemi head inline six in their compact cars. I've wanted one since I heard about them so I could reply, "Hell yeah, it's a HEMI!"
I had a duster gold 1972 with the slant 6 those engines were very reliable
77- 80 super 6 were all 2 barrel and a bigger exhaust manifold 2.25. Made a whopping 110 hp 180 ftlb torque
My Dad (RIP) had a 1978 LeBaron sedan with the Super Six. Of course, the EPA smog system choked it.
My Dad and our next door neighbor took the 2bbl off and put in different jets. I don't know what they did but, it definitely felt peppier and probably gave it an honest 120hp at the rear wheels as opposed to the claimed 110 hp in EPA form. The fuel economy dropped a bit but, the performance improvement was worth it.
Thanks for the Information.
The "Super 225" name was used on Plymouths and the "Charger 225" name was used on Dodges. They are otherwise identical engines. The Super Six was not available in the USA until the late 1970s because Chrysler did not want to cut into sales of the more expensive and powerful V8 engines.
I wish I had thought to mention all of that in the video....lol.
From the early 70s on, the nanny state govt. was telling car makers what they could sell in this country.
Plymouth had the Super 225 and Dodge had the Charger 225 and starting in 76 or 77 Chrysler put a 2bbl carb on the 225 and called it the Super Six and the only difference was the the intake and carb one had a single barrel and the other had a 2bbl intake and carb. The 2bbl carb was the same carb the 318 ran on it. It did not run the big 2 bbl like you would of found on the 360 CI engine.
It was a BBD, but NOT the same carb used on the 318,It had minor differences and flowed 75 cfm less.
Yeah we had a '68 Dart with a 225, and it said "CHARGER 225" on the air cleaner. Speaking of air cleaners you can fit a 10" element under one of those lids. If you buy an aftermarket base for a four-barrel carburetor with a 10" element, you can use those lids. That's what I'll be doing for the 225 in my '80 Mirada.
I had a 70 valiant 4 door sedan and mine had a 198 slant 6 no one seems to talk about the 198 for some reason it was rated at 125hp. The 225 was 145hp. And I don't think the 170 was available for 70' I think the 198 replaced the 170.
Not sure about the difference, but the first one needs the pushrods adjusted rather badly. The later Super Six was a 2bbl carburetor.
The 170 was standard engine in Valiant, Lancer, and later Dart. There was also a 194 variant. Having lived with 225 slant sixes, you are welcome to them. The 318 V8 gets better gas mileage and can get out of its own way.
198, not 194.
Sweet car. I love the fact that it still has the original wheels, tires, and wheel covers on it. PLEASE don't put 22" GHETTOs on it. I would love to have that as a daily driver, IF it had A/C in it. I live in Phoenix, AZ, and for half the year A/C is an absolute necessity, not a luxury.
My family lives in PHX, know exactly what you mean. There, this would be a winter car, not a summer car.
I remember on the 1968 Dart, the sticker on the air cleaner housing said Charger 225, it must be a Dodge/Plymouth thing.
It was.
My grandfather's 79 Vol are wagon had the 225 Super Six 2 barrel
My 64 dart got says 225 charger. Have you heard of that ?
It's a marketing thing. Back then the 225 Slant Six was an option over the base 170 cid version and they wanted owners to be proud of it.
Actually, Chrysler feared the same thing that GM feared in the Pontiac OHC Sixes...that beefing them up would take away from more profitable V8 engine "upgrades", which typically were sold as part of a "package". That's where the PROFIT was in car sales. A "Super Six" simply didn't command as much money as a V8, even the "doggish" 318 2 bbl that seemed to power almost everything that Ma Mopar put out.
In 1960, the Plymouth Valiant had the 170 cubic inch as standard the 1969 year was the last year for the 170, Chrysler replaced the 170 with 198 cubic inch engine in 1970 then in 1980 dropped the 198 and only the 225 until it was dropped in 1987
As an owner of 2 cars with 20 years between them, I love the modern touchscreen and sensors etc, but love my old mk1 focus from 1999. If you didn't have a modern car from work, would you ever own one or would you stick with the classics as a main car?
I had a Super Six in a 1979 Chrysler LeBaron. It was the dirtiest running engine I ever had. If you left it idling in the driveway for 5 minutes there would be a little pile of soot under the tailpipe. If you stepped on it to pass someone and it downshifted there would be a giant cloud of black smoke coming out the back. I was just a kid in college at the time so I never had it looked at but I assume it was running super rich. It also only got 10-14 mpg depending on city or highway. It was a bit disheartening to only get 180 miles out of an 18 gallon tank.
Sounds like a bad choke pull off, I had that issue too resulting in black smoke out of the tailpipe.
Thats what my current 75 Dodge D100 is doing right now, about 10mpg on a rebuilt engine with the black tail pipe soot marks left on driveway as well. Have messed with the timing to no improvement; only thing I have not done yet is rebuilt the carb which is next on my list as soon as I get back from my deployment.
@@chadfield376 the choke pull off if I remember correctly has a vacuum that moves a mechanical linkage to keep the butterfly from completely closing while the choke is engaged.
The electric choke that Chrysler had in the late 1970s were horrible. I had a 1980 Aspen and found it best if you didn't press the throttle until it was fully warmed up or you were on the highway cruising. Did I see black smoke? Definitely! But if you pressed the throttle before it was warmed up, it would almost totally disengage the choke and you were left with a bogging engine when you tried to drive off again. I remember manually shifting the automatic in order to get going. What a pig. Everyone blamed Chrysler, but it was once again the Federal US government sticking their nose in their business for "cleaner air quality". Ironically, I believe that my 3 other older slant six engines that I owned with mechanical chokes were more cleaner for the environment and didn't have the problem.
If only they would have made the other half and done a v12! 😎👍
I bet they considered it.
I’ve heard that the 170 was by far the most durable Slant 6 made.
The rod bearing speeds are slower because of the shorter stroke.
According to "Uncle Tony", the 170's 3-13/32 bore by 3-1/8 stroke are just about perfect for that engine. That yields roughly a 10:9 bore to stroke ratio, which many engine designers say is the "ideal" for a modern engine.
Best engine ever
The slant six marine came with a 2 barrel
I did not know of a marine version. What were they used with?
Super 225 is a Plymouth and Charger 225 is a Dodge.
79 short bed dodge pickup had 225 super.
40 year's ago a friend bought a orange Dodge Charger that had 4 screws sticking up on the roof and the doors had oblong tale tell signs signaling that there had been a sticker on each side. Ok, I'll get to the point. It had been an Orkin Pest Control company car at one time. He didn't think much of his temporary cheep transportation and agreed to sell it to me when he got more money and got a new ride. I loved that car. Well, just about time he was fixing to get another car and sell the Charger to me the dumb butt got drunk, passed out at the beach, and a lowlife friend of his took off with a girl he'd picked up for a short joy ride and wrecked it bad. I was sick. It was not to be. I later got a 72 or 4, can't remember, Duster rust bucket northern car with the mighty slant 6 and had fun with it until it just about turned to solid rust. That's my story.
Thanks for sharing!
I am jellous I love this car keep it just the way it is no harm in that at all
I heard that the 170 cid engine is good for racing.😊
You got that right! You can take 100 thousandth off the head and get ride of that broomstick cam,dual exhaust and 2bl carb 4sp Tran 10.25 tempest clutch and you will scare the s__t out of your friends with 225. You will out rev 'em. It's the same comparison 170 vr 225 as 283 vr 327. Ask Joe Alread, look him up, he beat a lot of 327s
The super six engine was mute than just a 2 bbl carburetor upgrade….it had a hotter camshaft also
And do not forget the 198 cubic inch also .
absolutely
The honey of the taxicab fleet.
Smart man keep the Slant 6 225 in it..
Never mentioned the 198 cubic inch slant six !!!
I know about that engine, but why would I mention it? It has nothing to do with either of the engines discussed in this video.
That's a nice Valiant
My 70 Duster 225 1 barrel Holley never got better than 17 mpg. Even with Clifford headers and dual exhaust....
My 64 dart 225 gets 26 at 75 mph interstate 30 at. 55mph
My 83 d150 gets 22- 24 mpg. 4 speed OD manual, 2 bbl carb with out any lean burn. And thats with a worn out engine that burns 1 quart of oil in 200 miles and not enough compression to park on ANY incline in gear with out it rolling down hill.
Got to lean out that Holly with jets. My brother had the holly at 18 mpg, I had the Carter bbs at 24 hwy and no jetting.
On the super six had a cam change along with two barrel that resulted in 110 net hp fact bud.mr mopar
Just 1 two-barrel?
How ‘bout *TWO!* Two Webers…. Better mixture distribution??
Anything is possible. The Hyper Pak had a 4bbl on it.
@@TylersNeighborhoodGarage I *was* thinking about improving the “long and slanty” in the Dodge that way. Alas, accidents happen, and my health was starting to go then anyway…
Different days back in the 60s and much of the 70s. In that time, sixes were considered old faithful economy engines. Comptrollers and other frugal minded people/cheapskates bought them.
Rich people bought Ford V8s because they could afford to work on them all the time.
I sold a factory aluminum super six intake for $100.

The reason other countries got the better deals and different carbs and such is because we started the emissions crap in 1964 with the advent of the pcv valve but progressively got worse year after year Canada didn't even start any emissions until the late 70s. The aussies didn't start until the late 80 s were the only country burdened with this crap anyway to the extent that no other country comes close to
